<mwc-tab-bar> 
IMPORTANT: The Material Web Components are a work in progress and subject to major changes until 1.0 release.
Tabs organize content across different screens, data sets, and other interactions.
Material Design Guidelines: tabs
Installation
1npm install @material/mwc-tab-bar
NOTE: The Material Web Components are distributed as ES2017 JavaScript Modules, and use the Custom Elements API. They are compatible with all modern browsers including Chrome, Firefox, Safari, Edge, and IE11, but an additional tooling step is required to resolve bare module specifiers, as well as transpilation and polyfills for IE11. See here for detailed instructions.
